Most Popular In-N-Out Secret Menu Items

he In-N-Out secret menu is a collection of custom burgers, fries, shakes, and add-ons that you can order even though they don’t appear on the printed menu. These items use the same ingredients already in the kitchen but combine them in new ways for extra flavor, bigger stacks, or lighter low-carb builds. The most recognized secret menu items include Animal Style, Protein Style, Flying Dutchman, 3×3, 4×4, Cheese Fries, Neapolitan Shake, and upgrades like mustard-grilled patties, chopped chilies, and whole grilled onion.

1. Animal Style Burger

The Animal Style burger is the most popular secret menu order at In-N-Out. The patty is cooked with mustard on the grill, giving it a caramelized tangy crust, then topped with extra spread, grilled onions, and pickles for a richer, fuller flavor. Fans love how the sweetness of the onions and the extra sauce balance the savory beef. You can order it as a Double Double, 3×3, or 4×4, and many people add extra grilled onions or more pickles for extra crunch. Prices usually range from $4.70 to $7.50 depending on size, and calories typically fall between 750 and 1,300.

2. Protein Style (Lettuce Wrap)

Protein Style replaces the bun with crisp lettuce leaves, making it a lighter, low-carb version of any In-N-Out burger. The lettuce adds a fresh snap to each bite and lets the beef, cheese, and spread stand out more clearly. It’s popular among keto and gluten-free diners, and works well with the Cheeseburger, Double Double, and even larger stacks like the 3×3. The price matches the regular burger, and removing the bun cuts around 150 to 200 calories.

3. Flying Dutchman

The Flying Dutchman is a simple two-patty, two-cheese combination served without a bun or toppings. It delivers pure beef and melted cheese in every bite, which is why low-carb and high-protein eaters order it so often. Many fans customize it with grilled onions, chopped chilies, or even an Animal Style twist for more flavor. It usually costs between $3.50 and $4.00 and comes in around 520 calories.

4. 3×3 (Triple Triple)

The 3×3 stacks three patties and three slices of American cheese for a heavier, more filling version of the classic burger. The balance of meat, melt, and spread creates a richer taste than the standard Double Double. Common upgrades include getting it Protein Style, adding mustard grilling, or swapping in a whole grilled onion slice. Prices typically fall between $6.70 and $7.90, with calories ranging from about 900 to 1,100.

5. 4×4 (Quad Quad)

The 4×4 is the largest burger In-N-Out officially serves, built with four patties and four slices of cheese. It’s a bold, heavy, extremely satisfying order designed for serious appetites. Fans often pair it with Protein Style or mustard grilling for extra flavor. Anything larger than a 4×4 is no longer allowed after past oversized orders caused policy changes. The 4×4 usually costs $8.50 to $9.90 and exceeds 1,200 calories.

6. Mustard Grilled Burger

A Mustard Grilled burger adds a burst of flavor by cooking the patty with mustard directly on the grill. The heat caramelizes the mustard, creating a lightly crisp, tangy layer that deepens the meat’s flavor without changing the structure of the burger. Many fans upgrade it with chopped chilies or a whole grilled onion slice for even more texture. Pricing matches the regular burger, and calories stay the same as the standard build.

7. Grilled Cheese

The Grilled Cheese is one of the best vegetarian-friendly items on the secret menu. It comes with a toasted bun, melted American cheese, lettuce, tomato, onion, and spread, giving it classic In-N-Out flavor without the beef. It’s soft, rich, and surprisingly filling. Popular variations include ordering it Animal Style or adding chopped chilies. Prices usually range from $3.00 to $3.50, and calories sit around 380.

8. Double Meat

The Double Meat is a simple two-patty sandwich served without cheese. This version highlights the clean, savory flavor of In-N-Out’s beef and is a favorite among guests who avoid dairy or prefer a lighter build. It pairs well with mustard grilling or extra onions. The price is usually around $4.00, with roughly 450 calories.

9. Tomato Wrap (Rare Item)

A Tomato Wrap replaces the bun entirely with stacked tomato slices, creating a fresh and low-carb alternative to both the regular and Protein Style builds. The natural acidity of the tomatoes gives the burger a bright, refreshing taste. It’s a creative option, though not available at every location due to prep time and consistency. Pricing and calories vary based on the burger inside.
